Choosing between a 2BHK and 3BHK is not only about the property price. Interior design cost can also make a major difference to your overall home-buying budget. A 3BHK generally requires more wardrobes, storage, lighting, and furniture, while a well-planned 2BHK can deliver a premium look at a lower cost. In Chennai, interior costs in 2026 vary depending on the apartment size, material quality, design style, carpentry work, and level of customization. A practical planning budget for a 2BHK is around Rs 5 lakh–Rs 10 lakh, while a 3BHK may require around Rs 8 lakh–Rs 15 lakh for a standard-to-premium interior. Luxury specifications can take the cost considerably higher. These are indicative planning ranges. The actual quotation depends on carpet area, measurements, materials, hardware, design requirements, labor, and the scope included by the interior company.
2BHK vs. 3BHK Interior Cost at a Glance
| Interior Category | 2 BHK | 3 BHK |
| Basic | Rs 4-6 L | Rs 6-9 L |
| Standard Interiors | Rs 5-10 L | Rs 8-15 L |
| Premium Interiors | Rs 10-15 L | Rs 15-25L+ |
| Luxury Interiors | Rs 15L+ | Rs 25L+ |
The biggest difference is not necessarily the size of the living room. It is the additional bedroom and the amount of fixed furniture required.
Why Does a 3BHK Interior Cost More?
A 3BHK usually needs:
- Three wardrobes instead of two
- More bedroom furniture
- Additional storage
- More electrical points
- More lighting
- Larger false-ceiling coverage
- More study or work areas
- Additional decorative elements
For example, if a homeowner spends Rs 1.5 lakh on an average bedroom wardrobe and storage package, adding another bedroom can increase the interior budget substantially. Therefore, buyers should consider interior expenses along with the flat's purchase price, registration charges, furnishing, and other move-in costs.

Room-Wise Interior Design Cost: 2BHK vs. 3BHK
1. Modular Kitchen
The kitchen is one of the first areas where homeowners generally spend a significant portion of the interior budget.
- 2 BHK
- Rs 1.25 lakh–Rs 3.5 lakh
- 3BHK
- Rs 1.5 lakh–Rs 4.5 lakh+
The price depends on:
- Kitchen size
- L-shaped or U-shaped layout
- Number of drawers
- Tall units
- Pantry
- Hardware
- Shutter finish
- Countertop
- Sink area
- Accessories
Design idea
For a contemporary Chennai apartment, consider handleless or profile-handle cabinets, tall storage, and under-cabinet lighting to create a clean appearance while maximizing storage.
2. Master Bedroom Interior
The master bedroom normally includes a wardrobe, bed back panel, dressing area, and storage.
Estimated budget
- 2BHK: Rs 1 lakh–Rs 2.5 lakh
- 3BHK: Rs 1 lakh–Rs 3 lakh
A full-height wardrobe with loft storage can make better use of vertical space.
Design idea
Instead of spending heavily on an elaborate bed backdrop, combine:
- simple headboard, full-height wardrobe, warm lighting, and compact dressing unit.
3. Second Bedroom
In a 2BHK, the second bedroom can serve as a:
- Children's room
- Guest bedroom
- Study room
- Multi-purpose bedroom
Estimated interior budget:
- Rs 60,000–Rs 1.75 lakh+
In a 3BHK, the equivalent room may have additional storage or a study setup.
4. Third Bedroom in a 3BHK
This is one of the main reasons why 3BHK interiors cost more. The third bedroom can be designed as
Guest Room
Keep it simple with:
- Wardrobe
- Bed
- Side tables
- Minimal lighting
Children's Room
Include:
- Study table
- Bookshelf
- Wardrobe
- Storage bed
Home Office
Use:
- Built-in desk
- Overhead cabinets
- Bookshelf
- Cable management
- Ergonomic furniture
A multi-purpose design can help homeowners avoid spending unnecessarily on furniture that is rarely used.
5. Living Room & TV Unit
The living room creates the first impression of the home.
- 2 BHK
- Rs 75,000–Rs 2.5 lakh+
- 3BHK
- Rs 1 lakh–Rs 3.5 lakh+
Costs can increase with:
- Fluted wall panels
- Veneer
- Marble-look finishes
- Backlit panels
- Storage cabinets
- Designer partitions
Fresh design idea: Instead of a bulky entertainment unit, choose a floating TV console with a textured feature wall and concealed wiring. This makes smaller living rooms appear more spacious.
6. Wardrobe Cost
Wardrobes can become one of the largest components of an interior budget.
- 2 BHK
Usually requires two main wardrobes.
- 3BHK
Usually requires three wardrobes.
An approximate planning budget is
- 2BHK: Rs 1.25–Rs 3.5 lakh
- 3BHK: Rs 1.75–Rs 5 lakh+
The actual cost depends on wardrobe width, height, internal accessories, board specification, shutters, and hardware.
Budget tip: Use full-height wardrobes with loft storage instead of creating separate storage cabinets wherever possible.
7. False Ceiling & Lighting
False ceilings can improve the appearance of a home, but installing elaborate designs throughout the house can quickly increase the budget.
Better approach
For a 2BHK:
- Living room
- Dining area
- Master bedroom
- For a 3BHK:
- Living room
- Dining area
- Master bedroom
- Selected additional rooms
Use simple ceiling designs in bedrooms and reserve statement lighting for the living area.
8. Dining Area & Crockery Unit
- 2 BHK
- Rs 30,000–Rs 1 lakh
- 3BHK
- Rs 40,000–Rs 1.5 lakh+
A compact crockery cabinet with glass shutters can combine display and storage. For smaller homes, a wall-mounted crockery unit can save floor space.
9. Pooja Unit
A 2BHK may work better with a compact wall-mounted pooja unit, while a 3BHK may have enough space for a dedicated pooja area.
Approximate budget
- Wall-mounted unit: Rs 20,000–Rs 50,000
- Custom pooja unit: Rs 50,000–Rs 1.5 lakh+
Choose a design according to the available wall space rather than allocating a large portion of the interior budget to decorative work.
10. Entrance & Shoe Storage
The entrance is often overlooked during interior planning.
A simple foyer can include:
- Shoe cabinet
- Mirror
- Key shelf
- Seating bench
- Decorative wall panel
Approximate budget
Rs 25,000–Rs 75,000+
For compact 2BHK apartments, combine the shoe cabinet with a mirror and small seating area to save space.
2BHK vs 3BHK: Where Does the Extra Money Go?
| Interior Work | 2 BHK | 3 BHK |
| Kitchen | Rs 1.25-3.5L | Rs 1.5-4.5L |

How to Save Money on Interior Design in 2026
1. Spend on functionality first.
Prioritise:
Kitchen → wardrobes → storage → lighting → decorative elements
2. Avoid excessive customization.
Every customized curve, panel, and storage unit can increase labor and material costs.

A simple ceiling can work well in bedrooms.

Premium finishes can look attractive but may not always provide proportional value.

When comparing interior companies, check:
- Material specification
- Hardware
- Number of cabinets
- Wardrobe dimensions
- Kitchen accessories
- Electrical work
- Lighting
- Installation
- Transportation
- GST

The cheapest quotation is not always the cheapest project.
